Mid-century modern two-tone jewelry suite

This is a matching jewelry suite consisting of a bangle bracelet, a pendant necklace, and a pair of drop earrings, all featuring a distinctive two-tone silver- and gold-toned metal design with intricate engraved or etched motifs. The design prominently utilizes concentric circular elements, where larger outer rings frame smaller suspended or overlapping inner discs decorated with sunburst or starburst patterns. The metals exhibit a polished, reflective finish, combining white and yellow metallic tones typical of mid-century fashion jewelry. The necklace is suspended from a fine curb-link chain, while the earrings feature post backs with dangling circular drops matching the pendant motif. The bangle displays a similar engraved multi-panel pattern around its outer band. There are no visible maker's marks, hallmarks, or identifying signatures apparent in the image, meaning the identification relies entirely on stylistic observation. The overall aesthetic is heavily suggestive of the modernist and atomic design trends prevalent during the mid-20th century, consistent with the owner's unverified context that the set was purchased in Las Vegas during the mid-1960s to early 1970s. The set shows light surface wear consistent with age and careful handling, but no major structural damage, missing stones, or significant tarnish is immediately discernible from the photograph. Craftsmanship indicates mass-market fashion jewelry of the period utilizing stamped base metals rather than precious materials.

Based on what I can see in the photograph, this matching mid-century modern two-tone jewelry suite—consisting of a bangle, pendant necklace, and drop earrings—features distinctive atomic-style concentric circular motifs with engraved sunburst patterns. The owner identifies this set as having been purchased in Las Vegas during the mid-1960s to early 1970s. However, I cannot verify from a photo the exact period of manufacture or metal composition, as there are no visible maker's marks or hallmarks apparent. The estimate of $150-$250 assumes the user-supplied timeline and context are correct, placing it within the category of collectible mid-century fashion jewelry. General market demand for atomic and modernist unsigned costume jewelry from this era remains steady among vintage enthusiasts, though value largely depends on condition, visual appeal, and wearable charm rather than precious metal content, since the suite appears to utilize stamped base metals. If physical inspection reveals the set to be a later reproduction, replica, or mass-market copy 'in the style of' the mid-century period rather than a period-appropriate piece, the value would likely decrease to the $50-$100 range. To establish a more precise evaluation and confirm authenticity, I would need physical inspection to examine the weight, construction quality, wear patterns, and any hidden closures or subtle stampings that might be obscured in the image.
